Key Technical Points for the Management of Black-Skinned Chewing Cane in the Mid-to-Late Growth Stage
How should black-skinned chewing cane be managed in the mid-to-late growth stage? Please provide an introduction. The management goal for black-skinned chewing cane in the mid-to-late growth stage is mainly to promote thickening and sugar accumulation, so as to increase yield and improve quality. The specific technical measures are as follows: Fertilization.

The management goal for black-skinned chewing cane in the mid-to-late growth stage is mainly to promote thickening and sugar accumulation, so as to increase yield and improve quality. The specific technical measures are as follows:
Fertilization. In the mid-to-late growth stage, black-skinned chewing cane should be fertilized once every 15 days, mainly with complete nitrogen-phosphorus-potassium fertilizer and potassium fertilizer. Each time, apply 50-60 kg of nitrogen-phosphorus-potassium compound fertilizer and 20-30 kg of potassium nitrate per mu, applied as a drench with water, or broadcast after rain, or broadcast after irrigating the cane field once with a "horse-run water" (a quick flow-through irrigation).
Earthing up. After fertilization, shovel up the thin mud in the furrows and bank it around the black-skinned chewing cane plants to thicken the topsoil. This not only stabilizes and reinforces the plants to prevent lodging, but also promotes the growth of new roots and protects them, enhancing the absorption function. It also helps prevent soil moisture evaporation, reduces soil moisture loss, and keeps the soil moist.
Water storage. In the mid-to-late growth stage, black-skinned chewing cane has a very high water requirement. The furrows must be filled with clean water to more than two-thirds of their depth to ensure a sufficient water supply so that the black-skinned chewing cane can grow and develop normally.
Foliar topdressing combined with hormone spraying. In the mid-to-late growth stage of black-skinned chewing cane, a mixed solution of 1000x abamectin, 1000x acetamiprid, 600x thiodiazole-copper, 300x Zhefengbao, 1000x KT-30, and 300x potassium nitrate must be sprayed on the leaves once every 15 days, or a mixed solution of 1000x emamectin benzoate, 1000x imidacloprid, 1000x sugarcane disease wuzong, 1000x Zhemiaole, 1000x natural brassin, and 300x monopotassium phosphate, to promote thickening and sugar accumulation.
